Incomplete fuel combustion?!!?
I've just change my fuel brand and I'm getting a strange behavior from my engines...
I'm getting fuel drops coming out from the exhaust pipe whatever the engine rpm... I've got power, the engine temp is OK (around 120-130°c)... so what could be the problem?
Should I decide to lean my needles and the engine start to sound... lean...
(The fuel I'm using is a 30% nitro fuel used into 15cc Heli engine)
